This invention relates to improvements in the art of dumping grain and the like from a vehicle, such as a wagon or a motor truck, to a grain pit located beneath the floor or platform on which Vthe wagon or truck is supported.

Numerous wagon dumps are now in common use, the wagon or .truck to be dumped being moved to position Withrthe rear end of the truck over and adjacent to the opening in the upperend of the grain pit. Means is then provided for elevating the frontend of the truck so as to permit the grain within the body of the truck to fall fromV said body by gravity; Inv order to accomplish' this it is necessary that one end of the truck be elevated six feet or more above the floor." Means has to be provided for trucks of various lengths. This inclination is very objectionable on account of the emptying of the oil in the crank case of the truck through the universal and transmission bearings; also emptying of the cups or pans in the crank case of the proper amount of oil, which oftentimes results in engine bearings being burned out after the truck is again operated. Furthermore, oftentimes the carburetor is wholly or partly drained, theV gasoline `and oil leaking from the engine on to the floor, causing a fire hazard. Y o

It is, therefore, the object of my invention to provide improved means for causing the grain to flow from the body of the truck into' the grain pit without having to elevate the front end of the truck to anamount in excess of an inclination to which the truck is designed'to operate over hills in actual transportation.`

A vfurther object of my invention is to provide a very simple and inexpensive means lfor accompushing the unloading operation Vwhereby-the end of the body, wherein the said body may be' cscillatedV longitudinally vso as to cause a rapid shaking or oscillation of the body toward and from its open end, wherein material within the body will be set into motion insuch a manner that the material Will floW through its open, end into the pit by gravity.

My inventionconsists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter morefully set forth,

'pointed out in my claims, and illustrated in the improve-d device is attached thereto andthe' manner in which grain isv emptied from the vehicle body to the grain pit or bin.

Figure 2 is a detail enlarged sectional view of the rear end of the vehicle body of the top end of the'grain pit and the lattice work supported therein, showing in side elevation my improved devicefor imparting oscillation to said body and the manner-'in which the oscillator is connected to the vehicle bed.

Figure 3 illustrates a modified manner of'connecting the oscillator to the vehicle axis.

Figure 4 is a plan View of my improved 'device taken on the ilne 4 4 of Figure V2.' Y

Figure 5 is a detail sectional view taken on the line 5-5 of Figure 4'.

In the drawings I have used the referencernufA meral Ill to indicate the body Of .a vehicle or truck Il, and|2 the frontwheels of said truck,- andV I3 the back wheelsv of the truck. The said Wheels I2 and VI3 are` supported on an inclined platform lll,Y the forwardend of the said platform being substantially' six inches vabove the back end. At the back end of the ,platform I4 is Vprovided an opening vI5 in which is'mounted the -grate bars I6, and beneath the bars I6 is theusual grain pitl Formedjin the floor I 8 is afslot I9 in which is rotatably Ymounted a shaft 2'0, `said shaft being carried by lsuitable 'bearingsv 2l and 22'. Mountedvr on the inner end ofthe shaft 20 and between the bearings 2l is'an eccentric 23 which is nxed tothe shaft. Rotatably mounted on said eccentric 23 is an eccentric block 24, which is Y preferablyformed of two semi-circular pieces secured by bolts 25, providing means wherebythe block is detachably mounted on the eccentric. The upper member of the block v2li is provided with a clamp device 26, which is also formed of two semi-circular members secured together by bolts 21. VThe members 26 are designed to receive and be adjustably clamped toa tubular shaft 28 in Ysuch a manner` that the shaft may be adjusted longitudinally through the clamp device.

Slidably mounted in the member 28 is a rod 29 having secured to its inner-end a head 30 to which is pvctally mounted a clamp device 3l.

said clamp device 3l including a set screw 32 t wherein the clamp 3l may bedetachably securedv to the back edge of the oor 33 of the bed I0.

A set screw 34 is mounted in a collar 35 attached to the inner end of the tubular shaft 28 to provideV means for adjustably mounting the member Y 29 within the member 28. y As willV be readily seen from Figures `1 and 2, the rear wheels |3` of the truck are suDpOrted near one edge of the pit opening l5 with theivrear end of the bed JIU extending over said opening, Y

the vshaft 20 being mounted transversely across the floor I8 and on the opposite side of then opening I5 from which the wheels I3 are-supported, with the push rods 28 and 29 extending increasing or shortening its length to adapt the A' device to be used with various sized grain pit openings, andalso to be used in connection with trucks or Vehicles of Various lengths and shapes.

Another advantage of my device lies in the jfact that it is equally adapted to trucks or veacross the bars I6. From this arrangement it e win be seen that if the .shafted is rotated, then the eccentric 23 will be rotated, causing the push f rods 28 and 29 to be moved longitudinally and the A l body Illrtobe oscillated or reciprocated. Y u n An electric motor 3BA is mounted beneath thefloor' IB lby a suitable' bracket 31; A belt38 providesmans foi` transmitting powerfromrthe mo'A tor to a belt wheel 39carried by 'the outer end of the shaft 20,' and thusfprovide mechanical means for rotating 'said shaft, therebyy imparting short and rapid reciprocating movement to the wagon body. On account of said body b'eingcsup-k prtedat a slightly inclined position with *itsY front end slightlyabove 'its delivery end, -grain will readily flow from the'front end toward the delivery end vandthr'oglfi a suitable opening d0 inthe `naar end or the muy, said opening being formed byfrais'in'g the end 'gateidl any desired hicles of variouslengths and sizes, and also may be 4usedjust as eiciently with a semi-trailer attached V,to vthe rear end of the vehicle. By mounting 'the shaft 20 below the upper face of the licor '|8jit .wi'llr'eadily be seenthat when the g push rodv is disconnected from the rear end of the vehicle body, said push rod will lie substantially fonfthe upper surface ofthe floor and across thelgrain N-pitso that a vehicle may Abe vdriven over the said push rod' and' over th'e said shaft with the,r lwlieel'sz'of'4 the vehicleystraddling the push rod.; As soon as the `vehicle has been locatedwith the rear .wheel adjacent to the edge of the-grain pity the clampY device 3D is elevated into 'position'andg attachedto the rear end of the body, after which the .endgate 4| is elevated a slight distance to. provide an opening of the desired height; andra portion of tlie grain in the rear endbfthe box will be automatically deliv- Vered to the Vgrainfpit-by, gravity; When the distancathus providing means whereby Vgrain will be rapidly delivered from the vehicle body to the grain pit with a minimum amount of apparatusand a comparatively-.small 'amount of power required to produce'tlieoscillation.

In .Figure 3 I haveillustrated -the clamp de, vice 3| asbeing applied to the rear axle 42` of the vehicle instead of the jbacl; edge ofthe bed,

In Vthe drawings I have illustrated a shaft and an eccentric for operating la push rodlforY pro ducing the necessary Aoscillations to the back end of the wagonebed. "However, it will be seen thatv Various modifications might be substitutedwithout departing,fromfthe-general idea of supporting the front end Vof the wagon bed slightly higher than theA back end and their oscillatingrthe' wagon body, or 'the bottom thereof, to set the material within the wagon body into motion.` Y

Afterbeing -set into oscillatory'motion this material will readily -iiow toward the delivery end. vIngactual practice, all ofthe grain within the wagon bodyuis moved towards the delivery 'end and discharged therefrom, eliminatingthene-v: eessity f sweeping or using a shovelt'o'. finish the "cleaning ordelivery of the grain, as is usual-VA l'yrequired; in the ordinary type of I grain dump wherein the Yfront end of the body is elevated to such an angle that the material will-flow out' without vibration, this sweeping and extra work lie--V ing-'necessary with"`the ordinary grain dump due to the Vfact that'it is not `'practical to elevate the truck to .such a height `that this material would ow otreadily by gravity,asbefore stated, the elevation ofthe front end-of thet'ruck to a height of six feet being about the limit, and even then, ver-y undesirable conditions exist.v A

'One advantage of Yanyy improved device resides kin .the fact that it-tnay 'te 'easily and quickly in;

stenen 'in 'tnernnwynr any grain elevator new in'qcoznmon ilse, without the necessity of anygreat amount of Vreiod'ellir'ig. Sonie of these 1n'- grain ceasestofiiownthenV the shaft 2U is rotated and oscillations imparted to the body, causing .the remainderol the material to iiow to the delivery end. Y, t
